</u>
To find the missing number in the proportion, you have to isolate it the term of x from one side of the equation.
First, thing you do is switch sides.
Multiply by 21 from both sides.
Solve.
Multiply the numbers from left to right.
Use the order of operations.
PEMDAS stands for:
- Parentheses
- Exponents
- Multiply
- Divide
- Add
- Subtract

The required system of equations is
Step-by-step explanation:
We need to write a system of linear equations that has the ordered pair (1,4) as it's solution.
It means we need to find system of linear equations, which after being solved gives x=1 and y=4
Let the system of equations be:
I have made equations such that adding x+y gives 5 i,e (1+4=5) and subtracting x-y gives -3 (1-4=-3)
Now solving this system of equations to find value of x:
Adding eq(1) and eq(2)
Putting value of x=1 into eq(1) to find value of y
The solution set after solving system of equations is (1,4).
The required system of equations is
